LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

[Holstein]

Need help removing BIOS password from my Lenovo T480s 20L8
Serial : PC0V3ZRN
Motherboard: ET481 NM-B471 Rev 1.0
I tried using the patched but after programming the chip. Laptop did not turn ON and when i connect charger. Power button flash 3 times and then nothing happens. I programmed back the original file but it showing the same symptoms.
I removed the chip from the motherboard.

20L8-S4S00

I suggest you remove the battery, unplug the button battery, wait a minute, and then plug the button battery and main battery back. Now you should be able to post. That's how I solve similar situation today.

I have a T480s running Windows 11, everything is working, but the BIOS is locked. So I purchased a CH341A programmer, read the chip 3 times to make sure it's right, and then patched it with the auto-patch tool. Unfortunately, the laptop refused to boot and played a melody. I had to write the original bin into the chip; otherwise, I can not use my laptop.
Would like to know why and how to patch it properly, files provided.

Model: T480s

ok so never mind my post above because i found a patched version for the x1 carbon gen 5 that i could download. i'm working on gen 6 now.

i was having trouble with autopatch always having a problem with my dumps. i've been using ch341 programmer on linux. it was writing everything fine, but none of the dumps would patch.

i've been trying to figure out how to clean the me region, and had to switch back to windows, and in the process, dumped this x1 carbon gen 6 with asprogrammer. autopatcher patched it without complaining. i'm writing it to the patient right now.

Massive thank you for this. It worked a treat.

LENOVO THINKPAD T495 AFTER PATCHED BIN LAPTOP GETS BEEP AND BLANK SCREEN.

Ok, so I have Lenovo Thinkpad X1 Carbon Gen 5
type: 20K4-01XUS
Serial PF-0VQQ8V

i've been searching this thread for a patched version and the only one i found the link said invalid file or something.

i've been using the patched bios posted to clear supervisor passwords on two dozen laptops now.

for some reason, autopatch fails with bad bin file every attempt. but i can dump the original bios, program the patched version (downloaded from this thread), remove the password, reprogram the original dump, then celebrate.
i was also able to use the t560 patched bios to remove the password on a p50s since it is the same motherboard

will be learning the ec technique next as i have a few x1 carbon gen 7 and 8 to unlock. i did post about nuking a p53s i'll get back to that one later
